If I have more than 3 levels for my ordinal variables then I have N-1 increments?

Hi! guys,

I am doing the threshold model for ordinal variables. and I finished the variables for 3 levels. However, I need modify the script to another variable which contain more 5 levels. I sucess with saturated model wiithout increments It gives me 18 parameters : rMZ,rDZ,4 threshold for MZ1 4 threshold for MZ2,4 threshold for DZ1 and 4 threshold for DZ2,respectively. But I was stuck at ADE model. Some problems in increments.
